Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00602 | $0.00602 |
| Opus 5.5 | $0.00241 | $0.00241 |
| Sonnet 5.5 | $0.00120 | $0.00120 |
| Haiku 4.5 | $0.00060 | $0.00060 |
Grade A, and why
ctrlx-os-agent-skills AGENTS.md scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

ctrlX OS Agent Skill Repository
Start Here
- Device involved? → Check MCP first:
tool_search_tool_regex("datalayer|ctrlx")- Tools found → use them directly, skip REST/curl
- Not found → use workflows below
- Pick workflow from
workflows/that matches the task - Read
reference/AGENTS.mdfor platform rules before making assumptions - Use recipe from
recipes/when a concrete playbook exists - Confirm before any persistent change on a real device
Routing

Safety Rules
Safe without confirmation: reading docs, logs, local files, drafting commands/code/answers.
Require confirmation on real device:
- app install / remove / update
- network / firewall / VPN / certificates / users / storage changes
- service restarts, reboots
- any config write via REST, SSH, WebDAV, or Web UI
Folder Intent

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ctrlx-os-agent-skills AGENTS.md is an instructions file published in the GitHub repository gmantoha/ctrlx-os-agent-skills (6 stars, last pushed 1mo ago), licensed MIT. It adds 602 tokens to every session, about $0.0024 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
